Re: Uther card works on Apple IIplus with contiki

Hmmm, the Contiki screen drawing code uses the cc65 C-Library. That

to the video memory. Using the videx firmware instead would result in
way to slow screen drawing. Writing directly to the videx video memory
on the other hand is - as far as I know - quite complicated. And even
if you know how to do it your code might easily turn out to be too
large to fit into memory.

Best, Oliver

Damn. I hadn't really looked into this. I was guessing that cc65 used the existing firmware and would therefore be a pretty easy thing to implement. I guess my goal is a long way off.

Thanks
